Abstract

L'invention concerne un ensemble microphone directionnel dont une surface présente au moins deux orifices d'entrée audio, un microphone comprenant au moins deux entrées audio et un moyen de transport du son de chaque orifice d'entrée à une entrée audio respective, ledit moyen de transport étant creux et au moins sensiblement rigide. Cet ensemble microphone peut convenir à des microphones directionnels tels que ceux utilisés dans des prothèses auditives. L'utilisation d'un moyen de transport du son rigide est avantageuse du fait qu'il suffit simplement de presser ledit ensemble contre une plaque avant, au lieu d'assembler des tuyaux souples. L'invention concerne également la façon dont la forme du moyen de transport rigide (p. ex. diamètre, surface intérieure et courbure) influence la réponse en fréquence et la directionnalité des tubes ainsi que la façon dont le diamètre de l'orifice d'entrée influence cette directionnalité.
